If I were the interviewer, I would ask if you can see a problem with this solution, and then ask you for a more efficient (O(N)) solution.

And while you're at, can you stop space and time and develop the first programming language used on Mars and feed that back to us?

That's probably even less efficient than my Linq code!

But would that ever happen in a real life work environment?

a = 15
b = 5
a = a^b
b = b^a
a = a^b

Does anyone else think coding interviews are fundamentally broken?
